The Pololu Stepper Motor w/ 18Cm Lead Screw: Bipolar, 200 Steps/Rev, 42×38mm, 2.8V, 1.7 A/Phase is a NEMA 17-size hybrid bipolar stepping motor designed for precision linear motion applications. It features an integrated 18 cm threaded rod as its output shaft, transforming it into a linear actuator capable of open-loop positioning. The motor achieves a step angle of 1.8° per step, translating to 200 steps per revolution, and each phase draws 1.7 A at 2.8 V, providing a holding torque of 3.7 kg-cm.
The motor's lead screw extends 18 cm from the motor's face, facilitating linear movement without the need for additional shaft couplers or set screws. This design is particularly advantageous for applications in home-built 3D printers and CNC machines, where precise linear motion is essential. The included copper alloy traveling nut, equipped with a mounting flange and four threaded holes for M3 screws, moves 40 µm per full step, with the potential for finer resolution through microstepping.
This stepper motor is compatible with various stepper motor drivers, such as the MP6500 or AMIS-30543, which enhance its linear resolution capabilities. The motor's four color-coded wires are terminated with a JST XHP-4 connector, allowing for straightforward integration into projects. Additionally, the motor can be controlled via multiple interfaces, including USB, TTL serial, and I²C, when paired with suitable controllers. Note: The nut is not spring-loaded, which may result in backlash and loss of positioning precision during directional changes.
1x Copper alloy traveling nut (carriage nut) with a mounting flange featuring four holes threaded for M3 screws
Dimensions: 42.3 x 42.3 x 38 mm (not including the shaft)
If you are not satisfied for whatever reason with a Product you bought on the Site, it is possible to return it for refund within 30 days from the date you received it unless otherwise indicated in the Product listing. You must first advise the Vendor associated with your order in your account to obtain a return authorization (‘’RA’’) number before returning a Product.
